DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 326,320, datedSeptember 15',- 1885.

Application filed October 530, 1884.

T 0 M5 whom it may concern:

Be it known that I, JAMES E. NEWOOMB, of

Rock Island, in the county of Rock Island and State of Illinois, haveinvented certain new and useful Improvements in Door-Checks, of whichthe following is a description, reference being had to the accompanyingdrawings, in which- Figure 1 is a front elevation of a. door having myimprovement applied thereto. Fig. 2 is a top view of the same, showingthe relative positions assumed by the various parts of the device. Fig.3 is a side View of my improvement. Fig. 4. is a view of a modificationof the connection between the rod E and the lintel. Fig. 5 is a frontelevation showing an alternate form of the cam hereinafter described.

The object of my invention is to provide a simple, cheap, and durabledevice which will enable one to stop a door at any desired point in itsswing, and hold it firmly against any ordinary force, either of the windor other agency. To this end it consists in the combination andarrangement of parts fully described herein, and definitely pointed outin the claims.

In the drawings, A represents the door, and B the lintel thereof. 0represents a plate,which is fastened to the front side of the said doorupon its upper rail. This plate 0 is provided with the ears 0 0practically at right angles to said plate 0. These ears 0 c areperforated to form the bearings in which the pin D is permitted to turnfreely. The upper end of the pin D has drilled in it a hole,d,into whichthe rod E passes and slides loosely. The end of the rod E next thehanging stile of the door is free and of any desired length. The otherend of said rod is pivotally connected to the lintel through theinstrumentality of' the plate'e, or its equivalent. The plate e is setinto the lintel so that its lower edge is flush with the lower edge ofthe lintel, and thereby it does not interfere with the opening orclosing of the door. d represents a collar loosely surrounding the pinD, and sustained by the pin d passing through said pin D. To thiscollard is pivoted the swinging arm F, preferably bent or doubled, asshown in Fig. 3, the upper (No model.)

end of which is practically cam-shaped, as shown in Figs. 1 and 5.

The operation of my device is as follows: When the door is closed, thevarious component parts assume the relative positions shown in Fig. 1,and in the full lines in Fig. 2. As the door is opened, the rod E swingsfreely from its pivotal point at 6 out with the door. At the same timethe rod slips freely through the orifice d in the pin D, while the pin Dturns loosely within its bearings in the ears 0 0, thus enabling thedevice to adapt itself to any position the door assumes in its swing.When it is desired to stop and hold the door at any point, the operatorgrasps the cord G and pulls it to the right or left until the camshapedend f of the arm F engages with the ear 0 and forces the pin D downward,thus clamping the rod E to the upper side of the ear 0. The pressurethus applied of the rod E upon the ear 0 holds the said rod securely,and does not permit of any movement of said rod within the pin D, andthe swinging of the door is effectually prevented.

Fig. 4; represents an alternate form of connecting the rod Eto thelintel, 6 representing a screw-eye to be attached to the lintel abovethe lower edge thereof. 'The eye 6 incloses the eye formed on the end ofthe rod E. The form of connection shown in Fig.1fis,however, deemedpreferable.

Fig. 5 shows an alternate form of the cam by which the rod is clampedand its movement checked. f represents the cam pivoted at f. f and f 3represent arms rigidly attached to said cam, and g and g cordsattached,respectively,tosaid arms. The weight or head fflattached to thearm f, or a weight attached to the cord g, tends to hold the camnormally in the position shown, so that the rod E is free to slidewithin the pin D. A pull downward upon the cord g clamps the rod E, asin the preferable construction hereinbefore described, and the door isheld securely. A pull upon the cord 9 relieves the pressure upon the rodE, which is then permitted to slide freely within the pin D, and thedoor to swing'as desired.

The cam f is in the preferable construction made somewhat angular, asshown in Fig. 1, as the angles tend to prevent it from jarring pinturning freely in bearings attached to the door and a rod pivotallyconnected with the 1inte1,which rodslides freely within an orifice inthe upper end of said pin, with a cam pivoted to the lower end of saidpin, whereby a pressure is applied against said rod,which prevents itsmovement within said pin, substantially as and for the purpose setforth.
